Carmike Cinemas has pushed a shareholder vote on AMCÂ Entertainmentâ€™s $1.1 billion (including debt) purchase offer scheduled for today back to July 25 citing â€œongoing discussionsâ€ between the companies.This is the second postponement of a vote, originally planned for June 30 â€” and seems to suggest that thereâ€™s something to a Reuters report last night that says AMC might sweeten its $30 a share offer.Some of Carmikeâ€™s biggest shareholders have said that the current bid is too low, and vowed to vote against it. InvestorÂ advisorsÂ Institutional Shareholder Services and Glass LewisÂ also urged â€œnoâ€ votes.â€œClearly, [Carmikeâ€™s]Â Board continues to believe it does not have enough shareholder support to achieve the 50%+ needed to approve the acquisition,â€ says B. Riley analyst Eric Wold.Up to now AMC chief Adam Aron said that he was prepared to walk away rather than payÂ more. The economics of the dealÂ â€œget marginal very quickly for AMC above the $30 deal price,â€ he said this week. AMC is controlled by Chinaâ€™s Wanda Group.Those wanting more â€œhave an unrealistic view as to Carmikeâ€™s value to AMC, and their resulting price expectations are simply beyond what AMC believes is prudent to pay. We have said all along that AMC is a disciplined buyer, and that very much continues to be the case.â€He added that while he remained â€œcommittedâ€ to the agreement after making a separate $1.2 billion cash and stock bid for UK-based Odeon & UCI Cinemas, Â â€œthe likelihood of an AMC/Carmike transaction continues to be at considerable riskâ€ if shareholdersÂ hold out for more.With the Odeon & UCI pact, â€œwe win with Carmike, and we win without Carmike,â€ Aron told analysts.Carmike shareholders seemed to think that he was bluffing, that someone else mightÂ offer more, or that the company could do better by remaining independent. The stock closed yesterday at $30.59, above AMCâ€™s offering price.Wold says that he believes the gap between AMC and Carmike shareholdersâ€™ expectations â€œremains wide.â€AMC Â and Carmike say today that thereâ€™s no â€œassurances regarding the outcome of any discussions between Carmike and AMC regarding the previously announced merger agreement.â€
